  fts: Don't reindex FTS mails if .cache file is deleted

This means that if fts is enabled, "doveadm index" no longer adds mails
to dovecot.index.cache if it's deleted. However, it was rarely used for
that purpose. More likely due to a corrupted cache file all the mails were
unnecessarily being opened and reindexed.
